Abstract
Modulation and control of a cascade multilevel static synchronous compensator (STATCOM) configuration to improve
the quality of voltage generated by wind power systems are presented. The proposed STATCOM configuration needs only four
dc-link capacitors and 24 switches to synthesise nine-level operation. In addition to that, switching losses are further reduced by
splitting the voltage source inverter of the STATCOM into two units called the ‘bulk inverter’ and the ‘conditioning inverter’. The
high-power bulk inverter is operated at low frequency whereas the low-power conditioning inverter is operated at high frequency
to suppress harmonics produced by the bulk inverter. Fluctuations at the point of common coupling voltage, caused by sudden
wind changes, are suppressed by controlling reactive power of the STATCOM. Simulation and experimental results are presented
to verify the efficacy of the proposed modulation and control techniques used in the STATCOM
